I REVERSIBLE ruLoR M-MEAnsL' 7 Application-filed. August's, 1921. SerialNo. 496mm} Be it known that L WILLIAM ;,COCK, a citizen of the UnitedStatemresiding at'Cliica'pgo, in flthe county of Cook and State ofIllinois, have invented certain new and useful Improvements "inReversible-Q Fulcrum Means, ofwhichthe following is p a specification; Yi i i i i This invention relates to'a new. and improved brake beam, forrailway cars, and; more particularly to a reverslble;fulcrum for suchbeams andto the connection between said reversible fulcrums and'the com,

pression member of the brake beam. 1

lying in the inclination of ,thefiilerum I As is well known in the art,brake beams are required in two types; right hand and left hand, thedifference between the types Some brake beams are ma-de with'fulcrums.freelyrotatable about their axisyso that they may be changed fromflefthandto right hand.

' Brake beams of that 'character'are shown inmy prior application SerialN oi 4t7 6,382 filed June10tl1, 1921. The beam of this prior applicationComprises means for tightlyconnecting the fulcrum to the corn; pressionmember, but contains no means for if locking the fulcrum in eitherthe'right hand or left hand position.

It is an object of vthe presentvinventionI to provide new and improvedmeans adapt ed to connect a rGVBISlblQfLllCI'UInl tea brake beam'compression member insuch mannerfas to afford a tight connection: andfurther to provldetmeans for maintaining the fulcrum fixed in eitheritsrig-hthand p t p ,4 'Theseouringjmember, as best show .or,left handposition.
